freebsd-skq/usr.sbin/usbconfig/usbconfig.c
hselasky 0b8d792721 - Make the FreeBSD's USB library compile under Linux. 
- Fix a compile warning where the return value of a call
to a write() function was ignored.
- Remove redundant include files from userland USB header files.
- Add some now needed include files to various C-files.
